About food grade lube

2018-10-29 10:36:28 hits:

Food quality is directly related to people's life and health, for the food processing machinery needed for the lubrication of the main concern is to prevent the pollution of food, raw material for lubricants must be safety requirements stipulated in the relevant pharmacopoeia, pharmacology, are reference for these requirements on the current international American FDA (food and drug administration (FDA)) and the USDA (USDA) regulations and standards.

What is meant by the USDA?

USDA is United States department of AgricultureUsda regulates processing plants for meat, fish, poultry, eggs and rabbits, and beverage, beer, canning, cereal, dairy, baking, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, canning, cooking, cooking, cooking oil, fat, pharmaceutical, cosmetics, and pet food.

 

UDSA grades lube oil into H1 and H2 grades.

Class H1 - food accessible, composition (lubricating oil or antirust film) for equipment and parts where the lubricant may be in contact with the food.

Class H2 - no contact with food. Composition (lubricating oil or antirust film) is used for equipment and parts.

What is meant by the FDA?

FDA stands for Food & DrugAdministration, which regulates lubricant additives in accordance with Food grade 21 CFR Section178.3570 of the Federal Register.

Food grade lubricants and lubricants must comply with FDA regulatory standards. USDA is responsible for the certification of food lubricants and puts the certification information on the website of NSF (national health association of America) (WWW.NSF.ORG).

Food processing plant case

Small and medium-sized food processing enterprises in China sometimes use lard, peanut oil and salad oil to lubricate food machinery to meet their requirements of non-pollution.This is a conceptual error, such as vegetable oil, as an environmentally friendly lubricant with good biodegradability, reproducibility and good lubrication performance.However, the application of vegetable oil in food industry is restricted by its defects in thermal oxidation stability, low temperature performance and viscosity-temperature performance.

The use of vegetable oil instead of food grade lubricant is prone to the phenomenon of oil oxidation and deterioration, which is manifested as increased viscosity, decreased lubrication property, wear and corrosion of mechanical parts.In addition, once bad oil comes into contact with food, it will cause food pollution and threaten food quality and safety.Moreover, the lubricating property of edible oil is far less than that of professional lubricant. These things are used in high temperature and humidity environment, and will soon cause bacteria, mouldy and deterioration, producing toxic and harmful substances, thus contaminating food.

For example, if there is no low-temperature chain oil in the cold storage of food enterprises, it will be unable to operate normally because the oil is frozen.Every day a lot of food machinery, especially in meat processing plant, with plenty of water to flush, splashed equipment lubricating points of water easily absorbed by common additives of lubricating oil and lead to lubricating oil emulsion, and oil oxidation reaction at high temperature, coking, sludge and colloidal substances, disable oil quickly, lubrication failure, causing mechanical damage.
